• Abstract

  Branch canker and dieback of avocado has been a serious problem for avocado producing regions, and its etiology, epidemiology and management are still a challenge. Given the lack of information about this pathosystem in Brazil, the objective was to characterize the occurrence of branch canker and dieback in 15 avocado orchards, preferably in the State of São Paulo, evaluating the spatial …

• Abstract

  Corynespora cassiicola is the causal agent of the target spot in leaves of several cultivated species, especially cucumber, where reports of damage in greenhouse cultivation conditions have been very frequent. Due to the difficulty of disease management, related to the lack of information on the resistance of cultivars and the absence of registered pesticides for cucumber disease in Brazi…

• Abstract

  A major problem in the commercialization of avocados is the incidence of postharvest diseases, which coincides with the ripening of fruits. The main postharvest diseases are anthracnose (Colletotrichum gloeosporioides) and stem end rots (Lasiodiplodia theobromae, Fusicoccum spp. e Neofusicoccum spp.), called quiescent disease because infect developing fruit in the field and the symptoms e…

• Abstract

  The target spot, caused by Corynespora cassiicola, occurs in several cultivated species, being considered an important disease in cucumber. This project aims to determine the response of the cucumber to the target spot according to the age of the plant, seeking to avoid economic damage to producers and to present a recommendation for preventive management of the target spot with fungicide…
